IMPROVEMENT IN PERTILIZER-ATTAGHMENTS.

. p Y Aj/ WW Tov ALL W'HOM 1T MAY coNe'ERN: c,

I Be it known that I, C. C. FOSTER, of Odessa, in the county of New Castle, in the State of'Delaware, have v invented a new'and useful' Improvement in Fertilizer Attachments; and do` hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, making a part of this specification, in which- Figure 1 shows anelevation' view of my attachment.

Figurey 2, a transverse section of the same. a

The nature-of my invention consists in providing wheat-drills, and other like machines, with a boxvor attachment of simple construction, and by means of'which any fertilizing-substance,'such as phosphate of lime, ttc., can be sown without the help ofthe hand. f A

To enableothers skilledin the art to make and 'u sefmy invention, I will now proceed to describe its construction and operation. i I

A A is the framework or box of my phosphate-attachment. Itis a light wooden or metallic box, made somewhat in the shape of a hopper, with a lid, L L. j

B is the back of the hopper of any drill towhich I may attach my attachment A A, being securedl there by -means ofI screws, or otherwise. l

A series of rectangular holes, R H, with bevelled sides, B S, lis cut through bottom B/'of A A. Under 'i Bv', and -to correspond with each of the holes RH, are set-screw bearings, E V. A rectangular hole,- corresponding in size and shape to hole R H, is cut through each of said screw-bearings.

A shaft, S H, is set lengthwise, under and parallel to bottom B', and on said shaft is set a series of metallic rollers, M. Their diameters will determine the positinzof shaft S H, which must be so placed as to bring' the top of each roller to iit easy into each corresponding'reversed bearing.

The rollers, allequal in size, must be made 'so that, in their periphery, a number of recessesl are cut,so as to leave between each .two recesses a cutting or sharp edge. i i

Inside box A A, and near and parallel to its bottom, is placedashaft, S H/on which is set a series of pins, P, each one corresponding with one of the holes in bottom B', thelength of said pins,- P, beingso calculated that when Sl H revolves, the-Pins will not'toucli bott-om B. i

On both sides ofeach pin, P, and on S H,are slet propeller-shaped wings, W S, placed symmetrical, two by two.

One end ofS AH revolves in ajournal'set in that end of AA. The other end of S H runs clear through the other end of A A, and a pinion is keyed/on to outside end of S H. vSaid pinion P W gears with another pinion, P W', of same diameter, keyed on outside end of S H, the other end of said shaftbearing a coglwheel, CW, which is togear with a pinion on the inside face of the wheel ofthe drill my attachment is applied to.

C W slides freely on end of S H, so as to be easilyeput in or out of gear, bymeans of lever L V. Between the back side of A- Aand. each roller is set a scraping-spring, S C P, for the purpose hereafter described. A f

Lastly, under each roller is placednl metallic or wooden cup, C P. v

Now, my attachment being attached to any drill, and being lle'd vwith the necessary phosphate, or any other .manure preferred, if the drill is driven ah'ead, cog-wheel C W,driven by pinion on the drillis wheel, will v drive S H, which, by means of pinions P W', will drive shaft S H. The phosphate in box AA being thus stirred, and moved, and'divided, or by as many hands, by means of Wings WPS, will fall through holes B Sv and R H. There, in consequence of the rotary movement of. roller R M, the sharp edges on periphery of which form, with the sharp edges of hole on bearing R V, as many cutters, which will all the time mince or separate the phosphate very tine, and drive it down through cups, C P, and thence with the grain to the ground, the object of the scraper-spring S G P being to keep the recesses or rollers constantly clean, andprevent the phos phate, if wet, to clog there, andll said recesses up.

Having thus. described my invention,"what I claim, and desire to secure by Letters Patente? the Unted States,v vis Y 1. The mode of sowing phosphate, or any like manure, by moans of an attachment,

ated as above described, or any other substantially the same.

2. Wings W S, combined with pins? and shaf S H', for the purpose and in the manner above setlforth constructed and operand described.

3. Rollers R M, springs S `C P, reversed bearings R V, the whole combined, constructed, and operated i'n the manner and for the purpose above set forth and described.
